Abstract: The well resistance affects the rate of consolidation of treated ground, the discharge capacity of prefabricated vertical drains relates directly to the well resistance; the smaller discharge capacity, the more well resistance; but the more discharge capacity, the more costs of prefabricated vertical drains. In this paper, the effect of consolidation due to the discharge capacity of vertical drains is analyzed; and the method for selecting the discharge capacity of prefabricated vertical drains for different treated ground is given. It is suggested that the discharge capacity of prefabricated vertical drains satisfying can be the criteria whether to consider the well resistance or not.

Key words: weak ground, prefabricated vertical drains, discharge capacity, well resistance
